MACHINE FOB. TRETING CUT PILE FABRICS.

Specification of Letters.P-atent. Patented June 29, 1920 Application filed January 1B.` 1917. Serial No. 142,992.

vtreating cut pile fabrics, such as chenille,

iixminster and Tilton rugs, and the like.

I-Ieretofore it has been customary in the vtreatment of such fabrics to submit them to the action of stiff bristle brushes for the purpose of removing` the loose fibers and aliniiig the pile fibers. This treatment has proved successful in removing some of the loose fibers, but it is impossible to remove them all in this manner. I have found, however, that by subjecting the fabric to a stiff scraping by a roll covered with sand paper, or other similar abrasive, itis possibleto thoroughly separate the fibers and remove the short strands. Furthermore, this treatment not only cleans and softens thev fabric, but also serves to'cause interiningling of the strands of adjacent varicolored tufts of the nap, which results in the assimilation of the colors, giving the appearance of the finest type of antique oriental rug. f

It is an object of my invention to provide a machine in which fabrics of this sort may be subjected to such abrasive treatment, which is at the same time both simple and efficient.

A further object is to provide means whereby the fabric being treated maybe moved into or out of contact with the abrasive at the will of the operator.

A still further object is to provide means whereby any of the parts of said machine may be rendered temporarilyl `ineffective without interfering with thel operation of the other parts. Y

Referring to the-accompanying drawings, Figure I, is a plan view of a machine constructed according t0 my invention.

Fig. II, is a side view of the same as see from. the left of Iiig. I. l

Fig. III, isa central cross section indi cated by the arrows III-III iny Fig. I.

In carrying out my invention I provide standards 1, and 2, united by suitable Atie rods 3, and 4. Driving shafti, is mounted in suitable bearings 6, and 7, on standards 1, and 2, respectively. Intermediate these standards shaft 5, carries scouring roll 8 which is securely attached thereto, and covj ered with sand paper' or other similar abra sive.

Pulley 10, is loosely mounted on the end of shaft 5, projecting" beyond standard 2, while pulley 11, is loosely mounted on theother end. Pulley 10, is connected with any apnropriate source of power (not shown.) and serves to drive shaft 5, by means of clutch 13. Clutch 13, is slidably mounted on shaft 5, and connected at 15, to arm 14, which is in turn pivoted at 16, to V shaped support 17, which extends outwardly from standard 2. Arm 14,- is alsopivoted at 18, to rod 20` which is slidably supported in a position parallel to shaft 5, by uprights 21, and 22, which extend upwardly fromstandards 1, and 2, respectively. Consequently, any mouvement of rod 20, to the lefttransmits a similar movement to clutch 13, serving to clutch pulley 10,v to shaft 5, while a reverse movement of rod 20, to the right releases them.

.Loose pulley 11, is also controlled by a similar clutch 25, loosely mounted on shaft 5, between pulley 10, and standard 1, `and connected to arm 26, at 27. Arm 26, is in turn pivoted at one end by bolt 28, to bracket 29, extending outwardly from .standard 1, and at the other to rod 30, by means of pin 31. In this way pulley 11, may be clutched or released by moving rod 30, either to the left or right. 1

Pulley 11, carries belt 35, thereby driving wheelSG, mounted on stud shaft 37. Also mounted on .shaft 37, is pinion 38, intermeshing` with gear 89, mountedV o n shaft 40, which extends between standards l, and 2. Pinions 44, and 45, are mounted on either end of shaft 40, and serve to drive sprocket wheels 46, and 47, by. means of chains 46,v

and 49, respectively. Sprocket Vwheels 46, and 47, are mounted on studs 51, and 52, projecting from standards 1, and 2, and carry pinions and 54. Pinions 53, and 54, intermesh with gears 55, and 56,'mounted on either end of shaft 57, pivoted in standards 1,'and 2. and whichcarries spiked feed roller `59, intermediate the two standards.

In this way roller 59, is driven from both ends, which does away with any torsional strain such as might result in warping or uneven motion.

Y At the opposite side of the machine, loose spiked roller G0, is similarly mounted intermediate standards l, and 2, on shaft 62, which carries pulleys 623, and 64, at either end. Over pulleys G3, and 64C, pass weighted strips 65, and 66, which are attached at one end to studs G7, and 68, projecting from standards l, and 2, respectively. These strips serve as brakes to constantly maintain the fabric under tension during its passage through the machine.

Mounted directly under roll 8, is ledger bar 70. This bar has a flat surface which extends the whole length of roll 8, and is attached at its ends to slide bars 7l, and 72, which are adapted to slide in guides formed in lugs 73, and 74, projecting' from standards l, and 2, respectively. rhe lower ends of' slide bars 7l, and 72, are pivotally connected to arms 75, and 7 6, which are in turn rigidly attached to rock shaft 7 8, journaled in standards l, and 2, respectively. To the outer ends of shaft 7 8, are rigidly attached treadles 8l, and 82, which project outwardly beyond feed roller 59. Treadles 81, and 82, are provided with counterweights 83, and 84, which tend to counteract the weight of ledger bar 70, but are not heavy enough to overbalance it. By depressing; either of the treadles to the position shown in the drawings, ledger bar 70, is raised to the position shown in Fig. III, where it is just short of Contact with roll S, being limited at this point by set screw 88 (see Fig. II) whereby the distance between bar 70, and scouring roll 8, may be regulated with great nicety. Bar 70, is also limited in its downward motion by stop S9, (see Fig. III) set on slide bar 72, in such a position as to come in contact with lower lug 74, when a convenient lower position of the ledger bar is reached.

In operation, the fabric 90, to be treated is passed over loose roller 60, to feed roller 59, and clutches 13, and 25, thrown in so that rolls 8, and 59, are both rotated. Feed roller 59, however, rotates much more slowly than roll 8, as a` result of the chain of gearing described, thus progressing fabric 90,

slowly in the direction of the arrows.`

Either treadle may then be depressed so as to bring ledger bar 70, into its upper position, and bring fabric 90, into contact with the lower edge of scouring roll 8, which is moving in the opposite direction to that of the fabric and at a much greater speed. In this way the pile tufts are separated by the abrasive carried by roll S, so that the short st 1ands of the nap are removed. At the same time, due to the fact that the fabric and the lower edge of roll S, move in the opposite direction, the pile fibers or nap of the fabric which formerly occupied approximately upright or indiscriminate positions, are now all laid in the same direction in the position shown in Fig. III.

lVhile the fabric is being thus progressed, the friction due to weighted straps G5, and 66, prevents loose roller 60, from rotating too quickly and holds the fabric taut. This is especially useful when the opposing force of roll 8, is first applied, as it has a tendency to slow up the travel of the rug. In this way I preserve an absolutely even travel of the fabric, while at any time it may be withdrawn from contact with scouring roll 8, by simply allowing the treadles to rise and ledger bar 70, to sink to its normal position. At the same time it is also possible to stop the travel of the fabric by moving rod 30, to the right and throwing out clutch 25, while the whole machine is stopped by throwing out clutch 13.

It will be noticed that this operation also is accomplished by moving rod 15, to the right, so that both clutches are thrown out by the movement of their respective bars :in one direction and thrown in by movement in the other direction, so that since the bars are placed in proximity a very simple and effective form of control is provided. Treadles 8l, and 82, are also located on the same side of the machine as rods 20, and 30, and project outwardly from the standards sufficiently beyond roller 59, to permit one person standing on that side of the machine to operate both the rods and treadles.
